Self-regulating system for urban road rainwater harvesting and utilization

Abstract

The invention discloses a self-regulating system for collecting and utilizing rainwater on urban roads. The permeable sidewalk and the hedge are provided with water leakage openings communicating with the hedge, and structural grooves are arranged under the permeable sidewalk; a humidity sensor is installed in the soil layer of the hedge. The upper part of the hedge is equipped with a regulator and a water pump, and the lower part of the vegetation layer of the hedge is provided with a water collection well. The water collection well and the water storage module unit are connected through pipelines. Movable cover plate and spring, the water collection well can be connected with the rainwater municipal pipe network through mutual regulation between the movable cover plate and the spring. The invention can automatically collect, purify and adjust rainwater, rationally utilize rainwater resources, not only relieve the pressure on municipal pipelines during heavy rain, enhance the ability of roads to resist waterlogging, but also reduce manual workload and save operating time, greatly improving the quality of the city. Utilization efficiency of rainwater resources.

Description

technical field [0001] The invention relates to a sponge city construction technology, in particular to a self-regulating system for urban road rainwater collection and utilization. Background technique [0002] Sponge city can be understood as a city that can be as "elastic" as a sponge. The sponge is just a figurative expression. The city itself responds to the advent of natural disasters. It has the functions of absorbing water, storing water, infiltrating water, purifying water, and discharging water. Rainwater can be accumulated through absorption, storage, infiltration, etc., and then stored when needed. The stored water is "released". When we encounter heavy rainfall, we can deal with it calmly so that the city can make full use of the rainwater; on the other hand, when the rainfall in our city is insufficient and the residents' living water is insufficient, we can use the rushing water source to benefit the urban residents, so that Make the movement of water in the...
